Question 67

The best suited hidden surface algorithm to deal with non-polygonal, non-planar surface patches is

  1. AZ-buffer algorithm
  2. BRay tracing algorithm
  3. CPainter's algorithm
  4. DScan line algorithm
Show answerHide answer

Correct answer: (A) Z-buffer algorithm

Explanation

The z-buffer method stores a depth value for every pixel, so it can handle any surface for which depth can be computed at each pixel, including non-polygonal and non-planar patches, with no sorting needed.
